Along the length direction of the first rotating shaft 2, a first pressing plate 4 and a first rotating plate 5 are provided on the first rotating shaft 2. The first pressing plate 4 and the first rotating plate 5 can rotate with the first rotating shaft 2. The first pressing plate 4 and the first rotating plate 5 are arranged parallel to the first rotating shaft 2, and an angle of 60 - 120 degrees is formed between the first pressing plate 4 and the first rotating plate 5.

The second pressing plate 6 and the second rotating plate 7 can rotate with the second rotating shaft 3. The second pressing plate 6 and the second rotating plate 7 are arranged parallel to the second rotating shaft 3, and an angle of 60 - 120 degrees is formed between the second pressing plate 6 and the second rotating plate 7. In this embodiment, a 90-degree angle is formed, that is, the first pressing plate 4 and the first rotating plate 5 and the second pressing plate 6 and the second rotating plate 7 are arranged in a mutually mirror image manner. Above the bracket 1, a vertically arranged hydraulic cylinder 8 is provided. The hydraulic cylinder 8 is located between the first rotating shaft 2 and the second rotating shaft 3. In this embodiment, the hydraulic cylinder 9 is located at the exact middle position between the first rotating shaft 2 and the second rotating shaft 3. At the bottom end of the hydraulic cylinder 8, a vertically arranged pressing plate 9 is fixed along the length direction of the first rotating shaft 2. Through the pressing plate 9, a downward pressure can be applied to the middle part of a rod-shaped or plate-shaped specimen, so that the rod-shaped or plate-shaped specimen is bent from the middle. When the first pressing plate 4 and the second pressing plate 6 are in a vertical state, the two ends of the rod-shaped or plate-shaped specimen can be respectively supported on the tops of the first pressing plate 5 and the second pressing plate 6, so as to facilitate the pressing plate 9 to apply a downward pressure. To facilitate the placement of the rod-shaped specimen, a first card slot 10 is provided on the first pressing plate 5. The first card slot 10 is specifically arranged on the side of the first pressing plate 5 away from the first rotating shaft 2. A second card slot 11 corresponding to the first card slot 10 is provided on the second pressing plate 6. When placing the rod-shaped specimen, one end of the rod-shaped specimen can be placed in the first card slot 10 and the other end can be placed in the second card slot 11.

[0021] The usage method of the present utility model is as follows:

[0022] If bending a rod-shaped specimen, first place the two ends of the rod-shaped specimen 16 in the first card slots 10 of the first pressing plate 4 respectively, and place the other end in the second card slot 11 of the second pressing plate 6, and make the part of the rod-shaped specimen 16 that needs to be bent be located directly below the pressing plate 9. Then, extend the hydraulic cylinder 8 to make the pressing plate 9 move downward to squeeze the corresponding position of the rod-shaped specimen 16, so that the middle part of the rod-shaped specimen 16 bends downward. As the pressing plate 9 descends, when the bottom end of the pressing plate 9 contacts the first rotating plate 5 and the second rotating plate 7, make the first rotating plate 5 and the second rotating plate 7 rotate downward, and drive the first pressing plate 4 and the second pressing plate 6 to rotate towards the pressing plate 9 through the first rotating shaft 2 and the second rotating shaft 3, and squeeze the two ends of the rod-shaped specimen 16 towards the pressing plate 9 by the first pressing plate 4 and the second pressing plate 6 (as Figure 3 shown), finally making the two ends of the rod-shaped specimen 16 abut against the pressing plate 9, completing the 180-degree bending of the rod-shaped specimen 16.

[0023] Through this device, the 180-degree bending of rod-shaped or plate-shaped specimens can be completed at one time, meeting the relevant experimental requirements, and the use effect is good.
